This is a project I found on another art blog. http://laughpaintcreate.blogspot.com/2011/08/city-prints.html This was a fourth grade project that reviewed warm and cool colors. It was also fun for the children to print. We painted the background the first week and then started work on our printing plate (foam). The next week we finished our drawing of the city and printed. They really came out nice and the children had a great time doing them.
